It sounds good. I ran only one event with my 29mm front bar and my AGX/sti spring setup and it was pretty decent. I'll let you know as I'm taking my Teins off the car this week and I can give you a bit of feedback on how the car turns in vs. with a smaller bar in the front. I've run now stock, 22, 24, and the 27/29mm. I like the 29 the best. My rear is at 24.
You're setting yourself up well to continue learning without spending a huge amount of money or losing daily driveability.
Currently I'm torn on whether I'll put the Teins back on the car with my 10k/12k setup next year. I'm tired of not having the car to drive around town because its too stiff and I get tired of having to tighten up suspension pieces constantly due to the stiffness. I'll probably end up putting them back on in order to be competitive at hte top of my region, but we'll see.
